Question

hich strategy would you choose to expand (x + 11)(2x + 3) and write an equivalent expression? Why? Be sure to explain your reasoning. *

Answer 1

Answer:

$2x^2+25x+33$

Step-by-step explanation:

Given: $(x+11)(2x+3)$

To expand: the given expression

Solution:

Use the formula: $(a+b)(c+d)=a(c+d)+b(c+d)$

In $(x+11)(2x+3)$, let $a=x,b=11,c=2x,d=3$

Put these values of $a,b,c,d$ in the formula mentioned above.

Therefore,

$(x+11)(2x+3)\\=x(2x+3)+11(2x+3)\\=2x^2+3x+22x+33\\=2x^2+25x+33$

So, an equivalent expression is $2x^2+25x+33$
